Echo: apache-airflow: security update to 3.2.2

low Tenable Cloud Security Plugin ID 462840

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Exploitation requires the attacker to already be an authenticated Airflow worker holding a valid Log-
 server JWT issued for at least one Dag. Apache Airflow's Log server authorized JWT tokens against Dag IDs
 by applying Python's `str.lstrip()` to the requested path segment when verifying the JWT's `sub` claim.
 `str.lstrip()` strips any of a *set* of characters from the left (not a prefix), so a JWT issued for a Dag
 named e.g. `dag_a` would authorize log access to any other Dag whose name began with any subset of the
 characters `{d, a, g, _}` (e.g. `dag_attacker`, `aaaa_target`, `_dag_secret`). Such an authenticated
 worker could enumerate and read worker logs of other Dags whose names happened to share that character-
 class prefix, leaking task output and error traces beyond the documented per-Dag isolation boundary.
 Affects deployments relying on per-Dag log-access scoping (multi-team, shared-executor, shared-worker
 topologies). Users are advised to upgrade to `apache-airflow` 3.2.2 or later. (CVE-2026-45426)

Solution

Update the apache-airflow library and its related packages to version 3.2.2 or later.
